- * NOTE: memory shared between threads is synchronized by all atomic operations
- * below, this means that no explicit memory barrier is required: all reads or 
- * writes issued before android_atomic_* operations are guaranteed to complete
- * before the atomic operation takes place.
+ * A handful of basic atomic operations.  The appropriate pthread
+ * functions should be used instead of these whenever possible.
+ *
+ * The "acquire" and "release" terms can be defined intuitively in terms
+ * of the placement of memory barriers in a simple lock implementation:
+ *   - wait until compare-and-swap(lock-is-free --> lock-is-held) succeeds
+ *   - barrier
+ *   - [do work]
+ *   - barrier
+ *   - store(lock-is-free)
+ * In very crude terms, the initial (acquire) barrier prevents any of the
+ * "work" from happening before the lock is held, and the later (release)
+ * barrier ensures that all of the work happens before the lock is released.
+ * (Think of cached writes, cache read-ahead, and instruction reordering
+ * around the CAS and store instructions.)
+ *
+ * The barriers must apply to both the compiler and the CPU.  Note it is
+ * legal for instructions that occur before an "acquire" barrier to be
+ * moved down below it, and for instructions that occur after a "release"
+ * barrier to be moved up above it.
+ *
+ * The ARM-driven implementation we use here is short on subtlety,
+ * and actually requests a full barrier from the compiler and the CPU.
+ * The only difference between acquire and release is in whether they
+ * are issued before or after the atomic operation with which they
+ * are associated.  To ease the transition to C/C++ atomic intrinsics,
+ * you should not rely on this, and instead assume that only the minimal
+ * acquire/release protection is provided.
+ *
+ * NOTE: all int32_t* values are expected to be aligned on 32-bit boundaries.
+ * If they are not, atomicity is not guaranteed.

+ *  - add blksize field to fuse_attr
+ *  - add file flags field to fuse_read_in and fuse_write_in
+ *
+ * 7.10
+ *  - add nonseekable open flag
+ *
+ * 7.11
+ *  - add IOCTL message
+ *  - add unsolicited notification support
+ *  - add POLL message and NOTIFY_POLL notification
+ *
+ * 7.12
+ *  - add umask flag to input argument of open, mknod and mkdir
+ *  - add notification messages for invalidation of inodes and

+/* README
+ *
+ * What is this?
+ * 
+ * sdcard is a program that uses FUSE to emulate FAT-on-sdcard style
+ * directory permissions (all files are given fixed owner, group, and 
+ * permissions at creation, owner, group, and permissions are not 
+ * changeable, symlinks and hardlinks are not createable, etc.
+ *
+ * usage:  sdcard <path> <uid> <gid>
+ *
+ * It must be run as root, but will change to uid/gid as soon as it
+ * mounts a filesystem on /mnt/sdcard.  It will refuse to run if uid or
+ * gid are zero.
+ *
+ *
+ * Things I believe to be true:
+ *
+ * - ops that return a fuse_entry (LOOKUP, MKNOD, MKDIR, LINK, SYMLINK,
+ * CREAT) must bump that node's refcount
+ * - don't forget that FORGET can forget multiple references (req->nlookup)
+ * - if an op that returns a fuse_entry fails writing the reply to the
+ * kernel, you must rollback the refcount to reflect the reference the
+ * kernel did not actually acquire
+ *
+ *
+ * Bugs:
+ *
+ * - need to move/rename node on RENAME
